"Loving the blonde... and by that I meant your fresh blonde hair," one commented.
"Excuse me while I pick my jaw up from the ground," joked another.
One even asked: "Did you get your boooobs done?" but Heidi replied confirming that she hadn't.
She looks drop-dead gorgeous regardless!
During her time on MAFS, Heidi was matched with electrician Mike Gunner, but their romance was far from a fairytale.
Though they decided to stay together during the final vows, the couple revealed at the post-finale reunion special that their toxic relationship had come to an end.
"Right after the final vows, Heidi and I went back to the Gold Coast together but it didn't take long and the wheels started coming off," Mike explained.
"We got to the end and we got to the final vows and we told each other that we loved each other, I moved everything to the Gold Coast and then it just went to s—t. It was great for like two days and then it just went to s—t. And then I haven't spoken to him since," Heidi added at the time.
However, the blonde beauty was part of the bridal party for the season's golden couple Jules Robinson and Cam Merchant at their official wedding in November 2019 along with Nic Jovanovic who was one of Cam's groomsmen.
Heidi, who works for 91.9 Sea FM on the Sunshine Coast, didn't find her Prince Charming on the show, but if you think she's going to try again for another shot at love on MAFS, think again!
In March this year, the radio host slammed returning contestant Lizzie Sobinoff for coming back, explaining that she didn't do it for the right reasons.
When 2020 groom Josh Pihlak made a guest appearance on her breakfast show and said: "Good on her for coming back and being able to do that," Heidi quickly disagreed.
"No, as if. You can't do it again. If you'd gone through it [before], you'd be like, 'Oh no,'" she replied.
